EUMETNET E-PROFILE: ceilometer cloud base height and aerosol profile data from NCAS's Lufft CHM15k "Nimbus" instrument deployed at Capel Dewi Atmospheric Observatory, UK
Abstract
Daily concatenated files of ceilometer cloud base height and aerosol profile data from National Centre for Atmospheric Science (NCAS)'s Lufft CHM15k "Nimbus" deployed at Capel Dewi Atmospheric Observatory, Uk.
These data were produced by the EUMETNET's E-PROFILE processing hub as part of the ceilometer and lidar network operated as part of the by EUMETNET members. This network covers most of Europe with additional sites worldwide.
The site has a corresponding WMO Integrated Global Observing System (WIGOS) id: 0-826-300-1. Prior to this a temporary WIGIS id 0-20000-0-03501 was used. See online documentation for link to station details in the Observing Systems Capability Analysis and Review (OSCAR) Tool.
EUMETNET is a grouping of 31 European National Meteorological Services that provides a framework to organise co-operative programmes between its Members in the various fields of basic meteorological activities. One such programme is the EUMETNET Profiling Programme: E-PROFILE. See EUMETNET page linked from this record for further details of EUMETNET's activities.

| Access rules: |
Access to these data is available to any registered CEDA user. Please Login or Register for a CEDA account to gain access.
Use of these data is covered by the following licence(s): https://artefacts.ceda.ac.uk/licences/cuncgl When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
Data were collected by instrument and transmitted to the central E-PROFILE processing hub at the UK's Met Office before preparation and delivery to the Centre for Environmental Data Analysis (CEDA). CEDA then produces daily concatenated files before ingestion into the CEDA Archive. |
| Data Quality: |
The data are provided as-is with no quality control undertaken by the Centre for Environmental Data Analysis (CEDA). The data suppliers have not indicated if any quality control has been undertaken on these data.
